Question

- A body is moving with velocity 30 m/s towards
east. After 10 s its velocity becomes 40 m/s
towards north. The average acceleration of the
body is
[AIPMT (Prelims)-2011]​

Answer 1

Answer:

acceleration =1 m/s^2

Explanation:

acceleration=final velocity - initial velocity /2

acceleration=40-30/2

acceleration=10/2

average acceleration=5

Answer 2

ANSWER: using the average acceleration formula: ️v=u+at

EXPLANATION:

U=30m/s,V=40m/s,t=10s

=40-30m/s÷10s

=10m/s÷10s

=0m/s^2
